  • p53 status : an indicator for the effect of preoperative radiotherapy of rectal cancer.
  • 1999
  • Ingår i: Radiotherapy and Oncology. - 0167-8140 .- 1879-0887. ; 51:2, s. 169-174

    • BACKGROUND: Rectal carcinoma is a common malignancy, with a history of high local recurrence rates following surgery. In recent years. preoperative radiotherapy and refined surgical technique have improved local control rates.AIM: To investigate the relationship between expression of nuclear p53 protein and the outcome in rectal carcinoma, with and without short-term preoperative radiotherapy.MATERIAL: Specimens from 163 patients from the Southeast Swedish Health Care region included in the Swedish rectal cancer trial between 1987-1990.METHOD: New sections from the paraffin blocks of the preoperative biopsy and the surgical specimen were examined immunohistochemically using a p53 antibody (PAb 1801).RESULT: Expression of nuclear p53 protein was seen in 41% of the tumours. The p53 negative patients treated with preoperative radiotherapy had a significant reduction of local failure compared with the non-irradiated p53 negative patients (P = 0.0008). In contrast, p53 positive patients showed no benefit from preoperative radiotherapy. The interaction between p53 status and the benefit of radiotherapy was statistically significant (P = 0.018).CONCLUSION: Expression of nuclear p53 protein in rectal carcinoma seems to be a significant predictive factor for local treatment failure after preoperative radiotherapy. Further investigations are necessary to select patients for preoperative treatment based on analysis of the preoperative biopsies.

  • Learning From Incident Reporting? : Analysis of Incidents Resulting in Patient Injuries in a Web-Based System in Swedish Health Care
  • 2020
  • Ingår i: Journal of patient safety. - : Wolters Kluwer. - 1549-8417 .- 1549-8425. ; 16:4, s. 264-268
  • Tidskriftsartikel (refereegranskat)abstract
    • Objectives Incident reporting (IR) systems have the potential to improve patient safety if they enable learningfrom the reported risks and incidents. The aim of this study was to investigate incidents registered in an IR system in a Swedish county council.Methods The study was conducted in the County Council of Östergötland, Sweden. Data were retrieved from the IR system, which included 4755 incidents occurring in somatic care that resulted in patient injuries from 2004 to 2012. One hundred correctly classified patient injuries were randomly sampled from 3 injury severity levels: injuries leading to deaths, permanent harm, and temporary harm. Three aspects were analyzed: handling of the incident, causes of the incident, and actions taken to prevent its recurrence.Results Of the 300 injuries, 79% were handled in the departments where they occurred. The department head decided what actions should be taken to prevent recurrence in response to 95% of the injuries. A total of 448 causes were identified for the injuries; problems associated with procedures, routines, and guidelines were most common. Decisions taken for 80% of the injuries could be classified using the IR system documentation and root cause analysis. The most commonly pursued type of action was change of work routine or guideline.Conclusions The handling, causes, and actions taken to prevent recurrence were similar for injuries of different severity levels. Various forms of feedback (information, education, and dialogue) were an integral aspect of the IR system. However, this feedback was primarily intradepartmental and did not yield much organizational learning.

  • Mortalitet bland sjukhusvårdade tycktes inte öka under sommaren [Mortality among hospitalized patients did not appear to increase during the summer]
  • 2019
  • Ingår i: Läkartidningen. - Stockholm, Sweden : Sveriges Läkarförbund. - 0023-7205 .- 1652-7518. ; 116
  • Tidskriftsartikel (refereegranskat)abstract
    • A retrospective review of medical records (2017-2018) at Linköping University Hospital compared hospital mortality for the 2-month period of summer vacations (group A) with two months of regular activity (group B). The mortality was 163 patients in group A and 216 in group B. Emergency admittance dominated (95%) in both groups. Comorbidity was found in 81%, and at admittance the risk for death during the hospital stay was estimated to more than 50% in three out of four patients. There was no difference between the groups regarding demography, hospital stay, or diagnosis. Due to a 30% reduction of hospital beds during the summer some patients were relocated to other specialties. No relocated patient died in group A but six in group B. Eight deaths were judged as probably preventable, but none definitely preventable. The similarity between the groups regarding mortality does not allow estimations of differences in adverse events in general. Low mortality among relocated patients is probably due to identification of high-risk patients not suitable for relocation.

  • Health related quality of life in Crohn's proctocolitis does not differ from a general population when in remission
  • 2003
  • Ingår i: Colorectal Disease. - : Wiley. - 1462-8910 .- 1463-1318. ; 5:1, s. 56-62

    • Objective  All treatment in Crohn's disease, although palliative, aims at restoring full health. The objective of this study was to compare health-related quality of life and psychosocial conditions in patients with Crohn's proctocolitis with a general population.Patients and methods  One hundred and twenty-seven patients with Crohn's proctocolitis (median age 44 years, 44.1% men) were compared with 266 controls (median age 45 years, 50.7% men). A questionnaire consisting of the Short Form-36 (SF-36), the Psychological General Well-Being Index (PGWB) and a visual analogue scale (VAS) evaluating general health as well as questions regarding psychosocial conditions was used. Disease activity was evaluated by Best's modification of the classical Crohn's Disease Activity Index.Results  Patients in remission had a health related quality of life similar to controls according to the SF-36 apart from general health where scores were lower (P < 0.01). Patients with active disease scored lower in all aspects of the SF-36 (P < 0.001 or P < 0.0001) as well as the PGWB (P < 0.0001). In a model for multiple regression including age, gender, concomitant small bowel disease, permanent stoma, previous colonic surgery, disease activity, duration, and aggressiveness, disease activity was the only variable negatively predicting all 8 domains of the SF-36 in the patient group (P < 0.001). The mean annual sick-leave for patients and controls were 33.9 and 9.5 days (P < 0.0001), respectively. Sixty-eight percent of the patients and 78.4% of the controls (P = 0.04) were married or cohabited, 67.7% and 78.0% (P = 0.04), respectively, had children.Conclusion  The health related quality of life for patients with Crohn's proctocolitis in remission does not differ from the general population. The disease has, however, a negative impact on parenthood, family life and professional performance.

  • Increased anal resting pressure and rectal sensitivity in Crohn's disease
  • 2003
  • Ingår i: Diseases of the Colon & Rectum. - 0012-3706 .- 1530-0358. ; 46:12, s. 1685-1689
  • Tidskriftsartikel (refereegranskat)abstract
    • PURPOSE: Anal pathology occurs in 20 to 80 percent of patients with Crohn's disease in which abscesses, fistulas, and fissures account for considerable morbidity. The etiology is not clearly defined, but altered anorectal pressures may play a role. This study was designed to investigate anorectal physiologic conditions in patients with Crohn's disease compared with healthy controls.METHODS: Twenty patients with Crohn's disease located in the ileum (n = 9) or the colon (n = 11) without macroscopic proctitis or perianal disease were included. All were subjected to rectal examination, anorectal manometry, manovolumetry, and rectoscopy. Comparison was made with a reference group of 173 healthy controls of whom 128 underwent anorectal manometry, 29 manovolumetry, and 16 both examinations.RESULTS: Maximum resting pressure and resting pressure area were higher in patients than in controls (P = 0.017 and P = 0.011, respectively), whereas maximum squeeze pressure and squeeze pressure area were similar. Rectal sensitivity was increased in patients expressed as lower values both for volume and pressure for urge (P = 0.013 and P = 0.014, respectively) as well as maximum tolerable pressure (P = 0.025).CONCLUSIONS: This study demonstrates how patients with Crohn's disease without macroscopic proctitis have increased anal pressures in conjunction with increased rectal sensitivity. This may contribute to later development of anal pathology, because increased intra-anal pressures may compromise anal circulation, causing fissures, and also discharging of fecal matter into the perirectal tracts, which may have a role in infection and fistula development.

  • Segmental resection or subtotal colectomy in Crohn's colitis?
  • 2002
  • Ingår i: Diseases of the Colon & Rectum. - : Ovid Technologies (Wolters Kluwer Health). - 0012-3706 .- 1530-0358. ; 45:1, s. 47-53
  • Tidskriftsartikel (refereegranskat)abstract
    • PURPOSE: Segmental resection for Crohn's colitis is controversial. Compared with subtotal colectomy, segmental resection is reported to be associated with a higher rate of re-resection. Few studies address this issue, and postoperative functional outcome has not been reported previously. This study compared segmental resection to subtotal colectomy with anastomosis with regard to re-resection, postoperative symptoms, and anorectal function.METHODS: Fifty-seven patients operated on between 1970 and 1997 with segmental resection (n = 31) or subtotal colectomy (n = 26) were included. Reoperative procedures were analyzed by a life-table technique. Segmentally resected patients were also compared separately with a subgroup of subtotally colectomized patients (n = 12) with similarly limited colonic involvement. Symptoms were assessed according to Best's modified Crohn's Disease Activity Index and an anorectal function score.RESULTS: The re-resection rate did not differ between groups in either the entire study population (P = 0.46) or the subgroup of patients with comparable colonic involvement (P = 0.78). Segmentally resected patients had fewer symptoms (P = 0.039), fewer loose stools (P = 0.002), and better anorectal function (P = 0.027). Multivariate analysis revealed the number of colonic segments removed to be the strongest predictive factor for postoperative symptoms and anorectal function (P = 0.026 and P = 0.013, respectively).CONCLUSION: Segmental resection should be considered in limited Crohn's colitis.

  • Surgery for Crohn colitis over a twenty-eight-year period : fewer stomas and the replacement of total colectomy by segmental resection
  • 2002
  • Ingår i: Scandinavian Journal of Gastroenterology. - : Informa UK Limited. - 0036-5521 .- 1502-7708. ; 37:1, s. 68-73
  • Tidskriftsartikel (refereegranskat)abstract
    • Background: This study describes how surgery for Crohn colitis developed between 1970 and 1997, towards the end of which period limited resection and medical maintenance treatment was introduced.Methods: A cohort of 211 patients with Crohn colitis (115 population-based), of which 84 had a primary colonic resection (42 population-based), was investigated regarding indication for surgery, the time from diagnosis to operation, type of primary colonic resection, risk for permanent stoma and medication over four 7-year periods.Results: Comparison of the periods 1970-90 and 1991-97 revealed that active disease as an indication for surgery decreased from 64% to 25% ( P < 0.01) while stricture as an indication increased from 9% to 50% ( P < 0.001). Median time from diagnosis to operation increased from 3.5 to 11.5 years ( P < 0.01). Proctocolectomy or colectomy fell from 68.8% to 10% of the primary resections, whereas segmental resection increased from 31.2% to 90%. At the end of the first 7-year period, 26% had medical maintenance treatment, steroids or azathioprine taken by 7%. Corresponding figures for the last period were 70% and 49%. Patients diagnosed during the last two time-periods had less risk for surgery ( P = 0.017), permanent stoma ( P < 0.01) and total colectomy ( P < 0.01). Findings were similar in the population-based cohort.Conclusions: Current management of Crohn colitis implies a longer period between diagnosis and surgery, a reduced risk for surgery and permanent stoma, and the replacement of total colectomy by segmental resection.

  • Sporadic adenomatous polyp regression with exisulind is effective but toxic : A randomised, double blind, placebo controlled, dose-response study
  • 2006
  • Ingår i: Gut. - : BMJ. - 0017-5749 .- 1468-3288. ; 55:3, s. 367-373
  • Tidskriftsartikel (refereegranskat)abstract
    • Background and aim: A 12 month, multicentre, randomised, double blind, placebo controlled, phase 3, dose-response study was carried out. Exisulind inhibits tumour growth by induction of apoptosis. The aim of our study was to investigate if exisulind induces regression of sporadic colonic adenomas. Patients and methods: A 12 month multicentre randomised double blind placebo controlled phase 3 dose response study was carried out. At baseline colonoscopy, left sided polyps (3-10 mm) were tattooed, measured, and left in place. Subjects received exisulind 200 or 400 mg, or placebo daily. Follow up sigmoidoscopy was performed after six months, and removal of any remaining polyps at the 12 month colonoscopy. The primary efficacy variable was change in polyp size from baseline. Results: A total of 281 patients were enrolled and randomised, 155 (55%) fulfilled the criteria for the intention to treat (ITT) analysis and 114 (41%) fulfilled the criteria for the efficacy evaluation analysis (patients who underwent the 12 month colonoscopy). The decrease in median polyp size was significantly greater (p = 0.03) in patients who received exisulind 400 mg (-10 mm2) compared with those who received placebo (-4 mm2). Complete or partial response was significantly higher in the exisulind 400 mg group (54.6%) compared with the placebo group (30.2%), and disease progression was significantly lower (6.1% v 27.9%) (p = 0.04 and 0.02, respectively). Increased liver enzymes (8.4%) and abdominal pain (14.7%) were also reported at a greater frequency in the exisulind 400 mg group. Conclusion: Exisulind caused significant regression of sporadic adenomatous polyps but was associated with more toxicity. This model of polyp regression, short in its term and involving a comparatively small patient sample size, may be the best available tool to assess a therapeutic regimen before launching into large preventive clinical studies.
